18 Claims.

Our invention relates to an apparatus for air conditioning.

It is the object of our invention to provide a unitary apparatus for the conditioning of air circulated to and from an enclosure, such apparatus being adapted to employ in the same mechanism either a heating fluid or a cooling fluid.

It is our object to provide in such connection a heating generator, such as a hot water generator, and an interconnected supply of cooling fluid as from a city water line or any other source of cooling or refrigerated liquid.

It is a further object to provide a unit in which the interior apparatus is supported as an integral unit separate from the outside enclosing casing and in which the outside enclosing casing is self supporting and is independent of the interior mechanism, both of such mechanisms resting upon a common foundation, thereby preventing the vibrations of the interior mechanism from being communicated to the exterior casing so as to reduce any noise of operation of the parts of the mechanism.

Figure 4 is a detail side elevationof one corner of the casing shown in Figure 2;

Figure 5 is an exploded view of the casing side walls showing the interior unit around which the casing side walls are located, the casing in this case being a modification. of the casing shown in Figures 2, 3, and 4; V

Figure 6 is a section on the line 6-6 ofFigure '7 showing in section the air conditioning unit;

Figure 7 is a section on the line 1-1 of Figure 6;

Figure 8 is a detail section of the spray nozzle and associated mechanism;

Figure 9 is a detail section through the duct outside casing and pipe connection to one of the radiators.

Referring to the drawings in detail, I is the floor of a building, such as the floor of a cellar, 2 and 3 are the side walls thereof, 4 is the first floor of the room 5 into which conditioned air is discharged and from which it may be withdrawn through suitable openings.

A thermostatic control 6 of any, desired charone form of acter is adapted to be plugged in at I which controls the operation 0! the motor 8 and the valve 9.

A hot water boiler used as a hot water generator designated generally l0 may be employed of any desired construction. This boiler is supplied with water for its make up fluid through the pipe II from the city waterline I2. This is controlled by the valve l3. The exit line from the hot water generator is designated l4. The outlet of such wateris controlled by the valve IS. The return 10 line is designated l8 and is controlled by the valve H. The outlet line H from the hot water generator has connected to it the branch l8 from the incoming city water line, which branch is controlled by the valve l9 and the introduction 15 of the cold water into the line [4 is controlled by the valve 20. The valve 2| controls the application of cold water to the humidifier spray casing 22.

When cold water is employed instead of hot 0 water from the hot-water generator, the cold water makes its exit through the line 23 controlled by the valve 24. This line 23 leads to a suitable outlet, such as the sewer. Turning to the air conditioning mechanism 5 per se, it will be noted that it consists of an air inlet chamber 25, the bottom of which is formed by a plate 26 supported on the bracket 26a and having apertures for supporting the filter stock- I ings 21 which are open at the top and closed at 36 the bottom through which air passes into the chamber 28. It then passes into the eye of the blower casing 29 where the blower 30 discharges air through the passageway 3| upwardly through the passageway 32 within the casing 33. The 35 blower casing 29 is connected to thecasing 33 by a c'onvas connector 34. Over the upper part of this connection is an outwardly and downwardly projecting flange 35 constituting a drip sheet extending the full length of the casing 33 to pre- 40 vent precipitate moisture from dripping upon, and soaking through-the textile material constituting the connector sleeve 34.

The connection between the stockings 21 and the supporting plate 26 is sealed by using a 45 pressed felt strip to close the space between the filter bag support 26 and the outside casing, a part of which is designated at 36. This felt seal is designated 31. I

In the wall of the casing 36 is an inspection 50 door 38. An air inlet passageway formed by the duct 39 discharges the incoming .air into the chamber 25, the top of which is closed by the supporting cap plate 40. It will be noted that the cap plate 40 supports the duct 39'. The side wall 36 has an interlocking lower side plate 36a. The duct 32 is provided with a drip catcher 4] which is drained by the discharge pipe 42 discharging into the cellar drain 43.

The duct 33 is supported by the angle iron supports 44. Mounted on the top of these supports and surrounding the top of the duct 33 is a collar 45, in which is telescopically mounted the duct or passageway 46 that is connected at its top by the flange 41 and bolts 48 to a cooperating flange 48 on the outlet duct 58. The restricted throat of the duct or passageway 46 is surrounded by the cap plate 48 but out of contact with it. This cap plate 48 overlaps the side walls of the outside casing, as hereinafter described, of which the side wall 36 and 36a is one part.

as eliminator plates for the removal of all entrained moisture from the air.

Both radiators 52 and 53 have plates, such as 53a, for guiding the air. The two sections of radiators are connected together by bolts 55 mounted in the side plates 56 and 51 of the radiators. These plates are connected to the sealing strips 58'which seal the space between the radiators and the adjacent walls of the duct 46. Such adjustable steel seal strips or plates 58 are so designed that they may be set in position to prevent the passage of air between the radiator and the casing 46. Bolts 58 hold these sealing strips in adjustable position. The lower radiator 52 is provided with feet 68 which rest upon the transverse angle iron support 6| while the other end of the radiator as at 62 rests upon a similar transverse angle iron support 63.

The inlet and outlet pipes to these radiators are sealed with respect to the ducts 33 and 46 by a means shown in Figure 9. This arrangement comprises a resilient ring 64 mounted on the duct wall by the clamping ring 65 and bolts 66.

. Humidifier The humidifier nozzle 54 is supplied with water from the pipe l8 controlled by the valve 2|. After the predetermined amount of liquid is determined by the setting of the valve 2|, the opening and closing of the humidifier is controlled by the solenoid valve 8. The water is admitted to a chamber 61 whence it enters a tubular member 68 threaded at 68 within the sleeve member 18 which has a detachable plug head 1|. This casing is provided with an overlapping flange 12 humidifying mechanism casing or any pipe con-' nection thereto.

upright angles 82 and the Outer casing With special reference to Figure 5, it will be noted that the casing sheets 36 and 36a, 11 and 11a, 18 and 18a, and 19 and 18a, are assembled 5 around the interior operating mechanism.

The lower sheets 38a and 18a are placed in position and then the lower sheet 18a, whose ends are suitably formed to overlap the ends of the sheets 36a and 18a as at 88, is placed in position and fastenedv byscrews 8|. The lower sheet 11a is then placed in position in the same manher.

The upper half of the casing is then similarly arranged comprising the parts 36, 18, 11, and 18. Then the cover 48 with its overlapping flanges 48a and having openings 48b and 48c is placed in position as indicated in Figure 6.

Referring to Figures 2,3, and 4 where there is an alternate method of constructing a casing where it is particularly adaptable to units of relatively small size, the complete casing assembly consists of the following parts: angle iron uprights 82 receive the sheets 83 and 84 and end sheets 85 and 86. A suitable access door 81 is provided. The cap 481s lowered into position.

.Around the inlet and outlet openings are angle iron collars 88 and 88.- The inlet collar 88 is drilled to receive attaching bolts for connecting the inlet duct39-thereto. In erecting this modifled form of. casing, after the interior operating mechanism has been erected, the angle iron uprights 82 are fastened to the side sheets 83 and 84 by screws 98. Then the side sheets are held in position and the two end sheets 85 and 86 are fastened to the angles 82 by the screws 88. The top sheet assembly 48 is then placed in position so that its reinforcing angles 8| rest upon the screws 82 are then inserted fastening the side and end sheets 83, 84, 85, and 86 to the angles 8L.

Method of operation When the hot water source is employed the valve I5 is opened and the valves l8 and 28 are closed. The hot water enters through the pipe l4 into the top radiator 56 and after circulating through that radiator passes downwardly through the pipe 52a, thence circulates through the radiator 52out through the pipe I 6 through the valve l1 which is open.

When cooling fluid is used the valve'l5 is closed and the valves .19 and 28 are open. The cooling fluidenters through the pipe 18 thence to the 55 radiator 53 through the pipe 52a, radiator 52 and pipe l6 upwardly through the pipe 23, the valve 24 being open and the valve l1 being closed.

It will be understood that the blower 38 is operated by the motor.

It will be understood that we desire to com prehend within our invention such modifications as may be necessary to adapt it to varying conditions and uses.
